That's exactly what I was thinking. I remember right before Metallica hit the stage I didnt wanna walk all the way to the bathrooms so I grabbed an empty plastic beer cup, stuck it down my pants and let my wiener do all the working and boom.....That's my piss break for ya

I did that for slayer at the barrier four years ago hahahaha, I did it during slayers set as well, and just threw it to the side then! The things we go through eh?
